It largely depends on the resolution of the sim in terms of particle density.
The general approach of meshing particles is using their distances to one
another. Usually it's a distance in all directions which means even there are
points that should belong to a "flow or string" in the fluids movement, they
will get meshed to nearby points if in a certain distance. Eric Mootz did some
RnD with a "principal component analysis" approach to drive the meshing more
towards the "flow of points" rather than the actual distance between single
points. Resulting in both, cleaner surfaces and some kind of "weighted meshing
by particle direction". So you can work with lesser particles, larger distances
between them and have a tighter mesh.
I think he released the emtools for free.
Otherwise I think theres only having more particles to get the meshing closer
to them (and have the mesh to be solid at the same time).

Subject: polygonizer and small particles
So I have some small particles I want to polygonize. Using the built in
version. I can't seem to get the mesh really tight/close to the particles. I
can get there a bit with some insane settings but its too slow and not close
enough. Is it sensitive to particle size in relation to SI units? Do they need
to be larger?
